  • the gas cooking appliance 600 further comprises a control unit 200 controlling the regulating valves 100'.
  • the control unit 200 receives the orders that the user enters through a user interface (not depicted in the drawings). If regulating valves 100 according to the first embodiment are used, there will not be a control device 200 acting on said valves because the user would act directly on the regulating valves.
  • the gas cooking appliance can be, for example, a gas cooktop, a gas cooker, a gas oven or a grill.
